Title: Magnetic disc device
Inventor: HOSOKAWA HARUHIKO
IPC: G11B21/10
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a positioning control system which incurs no degrading in a position error value even when abnormality is found in a position signal in a head positioning control of a magnetic disc device. SOLUTION: When abnormality is found in a position signal, a drive current balanced with an external force 16 in the radial direction of a magnetic disc 1, which is generated in a magnetic head 3 at a target data track position, is outputted as voice coil motor operation value 19. Otherwise, a position error value is defined to be 0μm or the position error value is estimated to set the position error value to an averaged value. As a result, a neutral operation value is outputted as voice motor operation value 15. Thus, even when the position signal detected is abnormal, the neutral voice coil motor operation value can be outputted and there is no transient response as caused by the abnormality in the position signal.

Abstract: PURPOSE:To increase the efficiency of dissolving chlorine gas into electrolyte by sucking chlorine gas remaining undissolved in either an electrolyte container alone or both an electrolyte container and the battery and blowing the thus sucked chlorine gas and chlorine gas produced from a hydrate into the electrolyte. CONSTITUTION:Electrolyte is circulated through a battery 1 in the direction indicated by the arrow by supplying the electrolyte from an electrolyte container 2 through a pipe 5 to the battery 1 by means of a pump 4 and then returning the electrolyte back to the electrolyte container 2 through a pipe 6.

Inventor: KUWABARA MASASHI
IPC: H01L29/74
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a vertical IGBT(insulated gate bipolar transistor) for power use of a trench gate structure, which can be reduced its on-voltage, without causing a reduction in its breakdown voltage and breakdown strength. SOLUTION: A low-concentration drift region 21 is formed on a drift region 12, base regions 13 are formed in this region 21 and emitter regions 14 are respectively formed in each of these regions 13. Trench gate regions 15 are formed to a depth, which penetrates the regions 14 and 13 to reach the region 21 and does not reach the region 12. Depletion layers in the vicinities of the regions 15 are easily spread by the region 21, and even if the regions 15 are deeply formed, a field concentration can be relaxed.  Therefore, as a reduction in the breakdown strength of an insulated gate bipolar transistor is hardly caused and the regions 15 can be deeply formed, the storage effect and conductivity modulation effect of carriers in the vicinities of the base regions 13 can be increased, and the on-state voltage of the insulated gate bipolar transistor can be reduced, without causing a reduction in the breakdown voltage and breakdown strength of the transistor.

Title: Angle of rotation detection circuit
Inventor: YOKOYAMA TOSHIO
IPC: G01B7/30
Filed: 1986-03-19
Abstract: PURPOSE:To detect the angle of rotation accurately, by a method wherein magnetoelectric conversion outputs are divided in voltage and amplified to be compared through an AC coupling circuit so that a comparison reference value will be the same as the divided voltage value of the magnetoelectric conversion output. CONSTITUTION:As a magnet ring 14 runs at revolutions a half those of a crank shaft synchronizing it, magnetic fields of magnetizing belts 22, 24 and 26 add to a Hall element 20 to obtain sine waves with a phase difference of 180 deg. at terminals 20c and 20d, which are differentially amplified 28. A bias of the amplifier is used to divide 28h the voltage of an output at the terminal 20c and the voltage at a point A is used. Then, after the DC component and a noise are removed therefrom with an AC coupling circuit 30, an AC waveform is made to overlap the DC voltage (bias voltage), applied to an inversion input terminal of a comparator circuit 32a while the voltage divided 32e at a point B is applied to a non-inversion input terminal to be made the same as the voltage at the point A and then, both are compared with each other. This enables faithful detection of a zero crossing position of the Hall element output and when an output of the coupling circuit 30 is lower than a reference value, an 'H' pulse is emanated. With such an arrangement, an angle of rotation can be detected accurately.
